Warning Sign (1985)
A government run research facility called BioTek Agronomics deals, on the surface, with genetically engineered corn that will improve farming considerably. But what the government is really doing is sponsoring a germ-warfare program which be can activated should the Soviets launch an attack on the USA. At the end of a normal working day the biohazard alerts appear on the monitor and security guard Joanie follows protocol and effectively puts BioTek on lockdown.
